A roadside concrete mixing plant with 4 hoppers and supporting facilities that transferred and produced the concrete that was used for the construction of the Sarcophagus. Some rubble with white tiles has been dumped on the site after the completion of the construction work, and is noticeably radioactive (~ 5 µSv/h).

МТС (машинно-тракторная станция)
A mechanic workshop where agricultural vehicles were maintained, refurbished, and scrapped for parts before the accident. During the cleanup it was used for the maintenance of vehicles used by liquidators, and the site has been abandoned ever since. Fertilizer machines, corn harvesters, and numerous other agricultural vehicles are now rusting away in a birch forest that is overgrowing them. There is a pick up truck with a trefoil logo on its door, a great place for a souvenir photo. For those interested, there are numerous radiation hot spots in and around the workshop, which can be found with a Geiger counter.
On the shore of the lake near the cooling water intake canal entrance is a fish hatchery with supporting buildings. Fishery was an economically interesting opportunity in the lake because it never froze over due to the elevated temperature of the water being used to cool the 4 operational reactors. This meant fishing was sustainable year round, and the fish caught were larger than elsewhere. The fish hatchery was abandoned after the accident, and one of the few buildings within a 5 km radius around reactor no. 4 that are not related to the power plant. The hatchery is not fenced off and can be visited, along with the remains of its floating dock. The shore offers a nice viewing point for the lake.
At the time of the accident, 2 more reactors of the same type as no. 4 were under construction to the south east of the existing 4 reactors. Construction was efforts were suspended indefinitely after the accident, and the nearly completed reactors were never fuelled. The structure is being dismantled as of 2019, but its half completed cooling towers remain. The northern tower is about twice as tall as the southern tower and can be seen from a distance. The concrete rebar sticking out from the top rim is a silent witness of the abruptness with which construction was halted.
Although radiation detectors (Geiger counters, etc.) tick at many places in the Exclusion Zone, most of the measured activity is very close to natural background levels or slightly above. There are however notable hot spots, where radiation levels are many hundreds or even thousands of times higher than background radiation. If you've never heard a Geiger counter tick, then these are perfect locations to test them out! If you're brave, a good location is this waste separation facility, with radiation levels of ca. 1 mSv/h close to the ground. The radiation is concentrated in an area of about 10 x 10 m. It's recommended to stay no longer than 5 minutes in the area, which should be more than sufficient to make a video recording of a ticking Geiger counter!

NSC
A 100-m-tall arch designed to replace the iconic sarcophagus as confinement structure to keep radioactive materials contained. It can be seen from a distance of kilometres away. You'll not be able to get too close, but the nearest observation point is 200 m away. The only way to get closer is if you are a scientist or a film maker that has had months of preparation in advance. Although radiation levels here will be much higher than elsewhere in the region, you will not be able to pick up a significant dose during your stay.
